FOA CFOT Certification Exam v11
True - Answer-A fiber optic inspection microscope can increase the danger of high powered light sources
by focusing the light coming out of a fiber into your eye. True or False?
True - Answer-A fiber optic power meter measures absolute power in dBM (dB referenced to 1 mw) and,
when used with a light source, can measure insertion loss expressed in dB. True or False?
core size, the diameter in microns - Answer-When we say 62.5/125 fiber, what does "62.5" mean?
cladding size, the diameter in microns - Answer-When we say 50/125 fiber, what does "125" mean?
Are "laser optimized" which gives more distance capability with gigabit networks using laser sources -
Answer-OM3 and OM4 multimode fiber with a 50/125 micron core are now a popular option in
premises cabling systems because they _____.
Higher - Answer-In-multimode fiber, the attenuation (reduction in optical power) of the fiber is _____ at
850 nm than at 1300 nm.
9/125 micron - Answer-Which of the following represents a singlemode (smaller core size) fiber size?
greater - Answer-Singlemode fiber has _____ bandwidth than multimode fiber.
large core step-index - Answer-Most plastic optical fibers are _____.
Primary buffer coating - Answer-When you strip singlemode or graded index multimode mode glass
fiber, you are removing the ____.

or tape to the ____ of the cable.
Both singelmode and multimode optical fibers - Answer-According to the references, hybrid cables are
cables that contain ____.
ribbon - Answer-What type of fiber cable design allows for large numbers of fibers with ultra-high
density, small size (diameter) and lower cost?
